My 17.5 hp engine cranks and idles good. But when I increase the throttle speed, the engine begins to spit and sputter. When under load (with the mower deck engaged ) it is even worse. It seems to be flooding and spitting back thru the carburetor although the choke assembly does not appear to be closed. I thought it may be a valve problem so I pulled the head, valves appeared ok, lapped the valves, reset valve clearences to specs, and installed new head gasket. Installed a new plug. Replaced fuel filter. Tore down carburetor for the fourth time and soaked all parts in carb cleaner. I reused all gaskets as they seemed to be ok.
Carb rebuild kit ~$40.00, new ebay carb ~$100.00 ( maybe less ).
Is it possible that it could be out of time due to the flywheel key ?
Has anyone experienced this?
Any suggestions. Please. Any help would be appreciated.
